Dolt is an open-source SQL database that behaves like a Git repository for data. Tables can be forked, cloned, branched, merged, pushed and pulled, and the command-line tool mirrors Git's commands. Dolt speaks the MySQL protocol, so existing applications and MySQL clients can connect without code changes. It is aimed at developers and data teams who need an auditable history of changes to their data. DoltHub is the platform where Dolt databases are shared, and Hosted Dolt offers a cloud-deployed instance.
DoltHub is headquartered in Santa Monica, California. As a US company it falls under US legal jurisdiction, including the CLOUD Act. The source code is published under the Apache 2.0 licence, so an organisation can run Dolt on its own servers or with a European cloud provider and decide where its data is stored. The vendor's public pages do not state in which regions Hosted Dolt stores customer data, so organisations that want to store personal data in that service should obtain the location in writing first.
